He was not wearing a helmet when he attempted the jump at Makaha Terrain Park, Aspen Skiing Co. spokesman Jeff Hanle said. No other details about the incident were released.

“Patrol responded immediately and found the man unresponsive with no pulse or breathing,” Hanle said, according to the Aspen Times. “They began advanced life-saving procedures. They were unable to re-establish a pulse and the man was pronounced dead by the Pitkin County Coroner.”

The park, which features about two dozen “intermediate and advanced” features and obstacles, was briefly shut down Sunday after the accident, the newspaper reported.
